How to create Wireshark logs

This guide explains how you can capture the network traffic. For this purpose, we recommend to create Wireshark logs about your system. Wireshark is a network packet analyzer program that can be used to capture any packet passing through your computer's network interfaces.

Wireshark is an advanced tool to analyze network traffic. Capturing network packets can be really helpful when you need to troubleshoot any problem that can be related to network communication. Thus you can easily discover what may cause issues when you are registering your devices or making VoIP calls.

How to make a wireshark capture

There are a few easy steps to follow if you want to create a wireshark capture (a .pcap file).

  1. Download the latest wireshark version from www.wireshark.org. There are separate releases for 32-bit and 64-bit operating systems. Make sure you download the appropriate version for your operating system.
